Combine broth, water and masa harina in crock pot and stir until lumps are mostly gone or gone. Than add the rest of the ingrediants except cheese and let cook on low for 6-8 hours or on high 3-4 hours. Add cheese approx. 30 minutes before serving to melt and then mix into stew. I serve in bowls with crushed tortilla chips, shredded cheddar cheese, a spoonful of salsa and a dab of sour cream on the top. If I have fresh cilantro I add some of that freshly chopped to the top also.
* You can substitute your own chopped cooked skinless boneless chicken breast meat, of course, about 1 1/2 lbs to 2 lbs.

Serves 6-8 at least, I have four children that are eating solids, lol and a hugry dh and we always have leftovers. :-)
